Description:
The overleftrightarrow is an ams-math function. However, Texvc treats it like it is a TeX function.
For example, <math>\overleftrightarrow{AB}</math> will throw the error " Failed to parse (PNG conversion failed; check for correct installation of latex, dvips, gs, and convert): \overleftrightarrow{A B}
Whereas, <math>\mathit{i}\overleftrightarrow{AB}</math> works.
I believe that the parser/tokenizer just needs to specify amsmath when it comes across \overleftrightarrow in the code. My workaround right now is dumb, such that I just force ams-math to be used in all latex processing.
